Check if pull needed in Git

Question

How do I check whether the remote repository has changed and I need to pull?

Now I use this simple script:

git pull --dry-run | grep -q -v \'Already

For the windows users who end up on this question looking for this, I've modified some of the answer into a powershell script. Tweak as necessary, save to a .ps1 file and run on demand or scheduled if you like.

cd C:\
git remote update                           #update remote
$msg = git remote show origin               #capture status
$update = $msg -like '*local out of date*'
if($update.length -gt 0){                   #if local needs update
    Write-Host ('needs update')
    git pull
    git reset --hard origin/master
    Write-Host ('local updated')
} else {
    Write-Host ('no update needed')
}
